Digital Brinell Hardness Tester HTB-3000
● HTB-3000 is a half automatic and intelligent Brinell hardness testing
machine, it adopts the pressure sensor to replace the traditional quality
weight, this innovative design makes the instrument more accurate.
● HTB-3000 selection of testing force and dwell time is controlled and
monitored on the front panel, it is automatic during the process of
loading, dwell and unloading.
● HTB-3000 adopts digital Brinell microscopes with adjustable LED
illuminator, it doesn’t need the operator to read the detail length of
indentation, it only needs operator to aim the D1, D2 diameter of
indentation and press the length key twice above the Microscope, then the
built-in computer can compute the Brinell scale and display the final
testing result on LCD display automatically.
● HTB-3000 doesn’t need the operator to read the detail diameter of
indentation and check the Brinell testing table, it improves the testing
speed and accuracy of hardness testing obviously.
